What is a combination wrench?

• A. A High Torque Wrench With Two Closed Ends.
• B. A Wrench With One Open And One Closed End.
• C. A Wrench With Ratchet Movement, Used With A Socket.
• D. A Tool Used To Tighten Or Loosen Allen Screws.

Answer: (B)

A combination wrench has two different ends on the same tool: one open-end and one box-end (closed end). The open-end slips onto the fastener from the side, which is handy in tight spaces or when you can’t fit a box-end around it. The box-end surrounds the fastener, giving a secure grip and distributing torque more evenly, which helps prevent rounding and allows you to apply more force. This combination makes it versatile for tightening or loosening nuts and bolts.

It isn’t a high-torque wrench with two closed ends, nor a ratcheting wrench that uses a socket, and it isn’t used for Allen (hex) screws.
